[THEORY] Scientist believe that the sun will stop burning and turn into a black hole in 5 billion years.
It is estimated that the sun formed into a star about 4.57 billion years ago.
It really is burning out, but there is so much gas in it that it will really burn out after about ten billion years.
it has been berning since the beginning of time
The sun is can be over 1,000,000 degrees. It is basically a large hydrogen bomg I outer space thathas been burning for 1,000,000 years and will countinue burning for 1,000,000,000 years.The gravity on the sunwould be enough too kill you instantly. But people have walked on the sun. George Washington was the first.
The sun is not actually burning as in a fire on earth, Burning is a chemical reaction that releases heat. The sun is a nuclear reaction. However most scientists estimate that the sun will continue to react brightly for another five billion years or so.
The sun is our local star. It is a giant fusion engine, and it is "burning" hydrogen and fusing it into helium at an enormous rate. But as long as it has fuel to drive the fusion process that is the sun's life, it will burn fuel continuously. It has been burning for about 4.5 billion years, and it has about that much more time left.
